Installing iPhone 3G GPS Antenna 



Tools used in this guide 

• Phillips #00 Screwdriver 

• Small suction cup 

• Spudger 




Step 1 - Battery 

• Remove the two Phillips #00 screws from the dock- 
connector end of the iPhone. 




Step 2 

• There is a rubber gasket between the silver 
front bezel and black display assembly. A bit 
offeree is required in this step to separate 
the iPhone's display assembly. 



G 



• Use a small suction cup near the Home button to gently 
pull up the bottom portion of the iPhone's display 
assembly. 

• If you don't have a suction cup, you may be 



able to use some wide scotch tape or 
something similar without too much glue.

Step 3 

• The display assembly is still connected to 
the iPhone by several cables, so don't try to 
remove it entirely just yet. 



& 



• Rotate the display assembly up until it is at an angle of 
approximately 45 degrees. 




Step 4 

• Continue to hold the display assembly with one hand, 
and use your other hand and a spudger to disconnect 
the black ribbon cable labeled "1."

steps

Step 6 

• Some iPhone 3Gs may have the connector 
colors reversed (black plastic tab, white 
connector). Make sure you're flipping up the 
tab properly, otherwise you may damage 
the connector. 



& 



• Use a spudger to flip up the white plastic tab holding 
the remaining ribbon cable in place. The white tab will 
rotate up 90 degrees, releasing the ribbon cable. 

• Slide the black ribbon cable out of its connector, and 
remove the display assembly from the iPhone. 

• Note: You may find on some versions of the 3G that the 
flip up plastic tab does not exist. In this case you would 
slide the ribbon cable towards the screen until it is 
removed. Upon assembly, you would apply pressure to 
the ribbon to insert it back into the ribbon "socket". 




Step 7 

• Insert your SIM eject tool or a paper clip into the hole 
next to the headphone jack. 

• Press down on the tool until the SIM card tray pops out. 

• Grasp the SIM card tray and slide it out of the iPhone. 




Steps 

• Use a spudger to disconnect the ribbon cable labeled

Step 12 

• Remove the following 8 screws: 

• Five 2.3 mm Phillips #00 screws with partial 
threads securing the logic board to the rear panel. 

• Two 2.3 mm Phillips #00 screws with full threads 
securing the logic board and camera. 

One 2.9 mm Phillips #00 screw from beneath the 
"Do not remove" sticker. 




Step 13 

• Use a spudger to gently pry the camera up and out of 
its housing in the rear panel. The camera cannot be 
removed entirely yet because it's connected to the 
bottom of the logic board.

Step 14 



• Use a spudger to gently pry up the end of the logic 
board closest to the dock connector. 



• If the board won't lift up, double check to 
make sure all the screws securing the logic 
board have been removed. 



c 




Step 15 

• Slide the logic board towards the dock connector and 
out of the iPhone. 




Step 16 

• Use a spudger to pry the battery up from the rear panel. 
The battery is attached with an adhesive strip around 
the perimeter of the battery. To prevent the battery from 
bending during the removal process, we recommend 
against using just the plastic pull-tab .

Step 20 



• Remove the four Phillips #00 screws securing the 
volume and vibrate buttons. 




Step 21 

• Lift the volume button circuitry away from the side of 
the iPhone, and carefully peel up the orange ribbon 
cable from the rear panel. 




Step 22 

• Carefully lift the headphone jack assembly out of the 
iPhone. 

• Switch the green mute switch down (towards the back 
side of the iPhone) into mute position. This will make it 
much easier to insert it, once the new mute button is in 
place.
